Access Your Computer Remotely . . . and It's FREE

LogMeIn allows users to perform functions easily - as if they were sitting in front of that machine . . . and it's free.

If you need to access a remote Windows computer, you could manage it with Windows built-in remote access services, but a much easier - and free - solution is to use a website like LogMeIn.
Visit the site, download its remote-access client software and install it on as many machines that you need to access. Once the software is installed, you can access those machines via your browser with an account that you create on the LogMeIn website. You'll be able to launch programs on the remote computer, open files, check your email and perform all sorts of functions as if you were sitting in front of that machine.

I (Bill Rogers) have used this for more than 5 years from locations all over the country. All you need is access to the Internet. I have at least 5-6 friends and business associates using it and they all rave about it. Yes, there is a paid version, but the free service does a great job.
